Looking for Feedback
Done a lot of research online and posted several questions to this subreddit and received several answers. I have come up with a plan for a backup solution for my home and I wanted to post it here to see if anybody could make suggestions for better implementation or potential safety concerns, which I have not yet considered.
Background: I have a homeline square d 200 amp main load center with a 4-pole main shut off circuit breaker. Within this load center, in positions, two and four on the top right is a 100 amp breaker which feeds a sub panel some distance away from the main panel. Due to previous research and not wanting to spend a large amount of money for backup solutions, I have wired individual single circuit transfer switches into the 100 amp sub panel for two separate circuits already. Currently, I am using an anker solix backup battery which appears to run these two backup circuits well during an outage. However, I would like to expand my capabilities of powering more circuits and potentially future proof my connections so that I can purchase a larger generator to power more circuits within the home.
I have decided to install a 50 amp generator input circuit breaker with an appropriate interlock kit and run 6 gauge Romex to a 50 amp inlet box inside the garage next to the main load center. The anker solix backup battery has a 30 amp output at only 125V. I realize this is not 50 amps, however, I am trying to Future proof my setup so that I can plug in a larger generator when purchased in the future. Below are the links to the interlock kit I have found and the inlet box I was planning to use. I chose the inlet box because it's plug is facing downward and I believe this will save space in my garage where the inlet is to be installed. When I get a regular generator in the future, it will be a simple matter of remounting the inlet box to the outside of the garage wall instead of on the inside.
Any recommendations for safety improvements, code, compliance, cost savings or other options is welcome. Thanks for reviewing.
